Description
Technical field
The present invention relates to a kind of display panels.
Background technology
Because therefore advantages such as the display panels tool is light, thin, power consumption is little are widely used in modernized information equipments such as TV, notebook computer, mobile phone, personal digital assistant.
Seeing also Fig. 1, is a kind of side sectional view of prior art display panels.This display panels 2 comprises one first substrate 21, one and this first substrate 21 second substrate 22 and the liquid crystal layer 23 between this first substrate 21 and second substrate 22 that are oppositely arranged.
Data line (figure does not show), a plurality of thin film transistor (TFT) 29 and one first alignment film 201 that is positioned at this data line and this sweep trace infall that this first substrate 21 comprises that many sweep traces that are parallel to each other (figure do not show), many are parallel to each other and intersects with this sweep trace insulation.This thin film transistor (TFT) 29 comprises a grid 291, one source pole 292 and a drain electrode 293.This first alignment film 201 is arranged on this first substrate, 21 inboards.
This second substrate 22 comprises a black matrix" 26, a plurality of colored light-filtering units 25, a common electrode layer 24, a plurality of first cylinder sept 27, a plurality of second cylinder sept 28 and one second alignment film 202.This second alignment film 202 is arranged on this second substrate, 22 inboards.
Seeing also Fig. 2, is the floor map of this second substrate 22.This black matrix" 26 is arranged on this second substrate, 22 inboards, and it is latticed and defines a plurality of viewing areas that are arranged.These a plurality of colored light-filtering units 25 are separately positioned in these a plurality of viewing areas.This common electrode layer 24 is arranged on this black matrix" 26 and these a plurality of colored light-filtering units 25.This first cylinder sept 27 and the second cylinder sept 28 are arranged on this common electrode layer 24, and be corresponding with the position of drain electrode 293 with the source electrode 292 of this thin film transistor (TFT) 29 respectively.This second alignment film 202 is arranged on this common electrode layer 24, this first cylinder sept 27 and the second cylinder sept 28, and its alignment direction is vertical with the alignment direction of this first alignment film 201.This sweep trace, this data line and this thin film transistor (TFT) 29 and these black matrix" 26 corresponding settings.
This common electrode layer 24 is the hyaline layers that adopt tin indium oxide or indium zinc oxide to make.This first cylinder sept 27 and this second cylinder sept 28 are the transparent cylinders with predetermined altitude that adopt macromolecular material to make, and the height of this first cylinder sept 27 is less than the height of this second cylinder sept 28.Wherein, this first cylinder sept 27 and this second cylinder sept 28 its height when compacted can reduce.
This second cylinder sept 28 is used for controlling the spacing of this two substrate 21,22, this first cylinder sept 27 is used for bearing partial pressure when this second cylinder sept 28 is compacted, is influenced the spacing of two substrates of this display panels 2 by excessive compression to prevent this second cylinder sept 28.
But this first alignment film 201 and this second alignment film 202 can be through the processes of a friction matching in the manufacture process of this display panels 2, common friction matching process be to use hairbrush according to alignment direction in alignment film surface brush mistake.When carrying out friction matching, because this first cylinder sept 27 and this second cylinder sept 28 have certain altitude, and this first cylinder sept 27 and this second cylinder sept 28 all are arranged on this second substrate 22, thereby can cause these colored light-filtering units 25 corresponding display orientations bad, and then influence the image quality of this display panels 2.
Seeing also Fig. 3, is the local enlarged diagram of this second substrate 22.The alignment direction of this second alignment film 202 is shown in arrow R among the figure.As seen, it is bad to have the subregion orientation along the R direction near this first cylinder sept 27 and this second cylinder sept 28.And the orientation defective region that this first cylinder sept 27 is caused and this colored light-filtering units 25 corresponding part viewing areas have the zone of coincidence 203.This coincidence zone 203 is the orientation defective regions that are positioned at the viewing area, and it causes the display frame quality of this display panels 2 to reduce.
Summary of the invention
For solving the lower problem of prior art display panels image quality, be necessary to provide a kind of display panels with better image quality.
A kind of display panels, it comprises one first substrate, second substrate and a liquid crystal layer this first substrate and second substrate between relative with this first substrate.This first substrate comprises a plurality of first cylinder septs and one first alignment film, and this second substrate comprises a black matrix", a plurality of second cylinder unit and second alignment film vertical with this first alignment film alignment direction.This first cylinder sept and the second cylinder sept and the corresponding setting in this black matrix" region.The orientation defective region that this first cylinder sept and this second cylinder sept are caused is corresponding with this black matrix" region.
Compared to prior art, the first cylinder sept and the second cylinder sept of display panels of the present invention are separately positioned on two substrates, so the orientation defective region can not have influence on the viewing area, thereby have better image quality.
